Do you mean the VPR, Vertical Polar Response, at the FRD consortium?

Try using this program. It is for baffle simulation, but will model multiple drivers also.

Then I would imagine the VPR program is what you would use instead of the ARPE program.
By the way, I tried the VPR program and it looks good, but I don't know how to read waterfall plots. So it was of limited usefulness for me. But perhaps not for you.
I think there is a thread around here somewhere about reading waterfall plots. Hmmmm.
PS: That Edge program looks very useful,AndrewJ. Thanks.
The problem with the VPR spreadsheet is that the response changes radically as you increase the number of samples per octave - yet, intuitively, it seems that by increasing the number of samples, the response becomes more accurate.kelticwizard said:
